I spotted this spider a few years back on a trail while out on a hike. But in the last few years they seem to have expanded their range and now I am finding them all around my home and the region I live in. People seem to be quite afraid of these spiders,

They are toxic, just like most spiders. But not enough to cause an issue unless allergic to their venom. You can see a smaller male Joro spider in the web as well in the above photo.
Joro spiders are excellent web builders, I commonly find prey in their webs. The webs can be quite large too, and the strands are amazingly strong. When I go to knock down the ones in the way I am always surprised how much effort it takes to knock down their webs. And commonly they just rebuild them over night if I dont kill the spider.
Sometimes the spider blends in quite well, do you see it in the above picture?
Here is another, it made a web over my Sweet potato beds and caught many White cabbage butterflies. I am thankful for that as they were quite the problem this year. I left some of them alone when they were helping out my garden.
Lastly a photo of a large female Joro spider, a smaller male and some food wrapped up by their web. They are now on the decline with the cooler weather coming around. But I expect to see them again next year. They seem pretty invasive, but with nature you never know how the pendulum will swing in the other direction. Maybe a new bird species will show up and start eating all these large spiders. But then who knows what the consequences will be of that.
